(David Kyle, 1976, Hamlyn) p151
Space 1999 is again, for the SF buff, inferior, with an unbelievable plot. It should be oh so much better than Star Trek because there isn't just a starship making the trip, it's Earth's entire Moon accidentally zooming around uncharted space discovering new planets, aliens and other unpredictable adventures. The old mistake of forgetting that it takes SF knowledge to write SF stories results in abysmally bad stories for Space 1999.

(Ed Brian Ash, Pan 1977)

Anderson's talents were later put to better use in Space 1999, a series with all the faults bequeathed it by those who call the genre 'sci-fi', but strong on special effects. Set on the Moon, which has been blasted out of orbit and is wandering through space, it has contained much questionable science but has also shown some story potential.

Les Brown, 1977 p406
SPACE;1999- syndicated hour long sci-fi series produced in England by ATV (1975-) and distributed in the US by its subsidiary, ITC. Produced on a large budget, part of which was justified by its showing on Britain's independent network, Space unabashedly sought to cash in on the Star Trek rage. Its cast was headed by American actors Martin Landau and Barbara Bain, a husband-wife team that had gained notice in Mission: Impossible. Rejected by the American networks, the show found a receptive market among individual stations, many of which were network affiliates. Space made a strong threat in syndication early in the fall of 1975, but the ratings soon flagged. Organic changes were made in the second year to improve its chances.

The changes included the addition of Catherine Schell to the cast and the hiring of Fred Freiberger, who had been associated with Star Trek, as producer. The second skein involved more action and greater use of special effects.

(a Starlog photo-guidebook, 1977) p85:
When Gerry and Sylvia Anderson first conceived Space:1999 they thought of it in terms of a British science-fiction show designed to appeal to American audiences. After every major American network turned it down, the plucky Andersons and ITC syndicated the series around the country.

Space:1999 lasted two controversial seasons. By mid-season, however, the science-fiction community was totally polarized in terms of the show. Space's fans were devout, touting the show as a great advancement for SF on TV (which it was). Its detractors claimed that the characters were wooden, the scientific aspects of the show were cockeyed and the scripts were sometimes inept (these charges also had basis in fact).

Despite the turmoil, the show triumphed in the ratings. But the flaws of the show led to a revamped second season, a revamping that some fans insist did the show in. Fred Freiberger replaced Sylvia Anderson as producer second time around. Freiberger was the man responsible for Star Trek's last season (Star Trek fans see a definite cause and effect relationship there) and was welcomed aboard because of his connection with that show.

Space's last season saw the addition of such characters as metamorph Maya (played by Catherine Schell) from the planet Psychon, and hero Tony Anholt, as well as the deletion of such roles as Bergman. Maya, who could transform herself into almost anything at will, was an attempt to make the interplay aboard Moonbase Alpha a bit more stimulating. Unfortunately, many saw her as being a token alien. Amidst a sea of finger-pointing, the show sank into oblivion at the end of its second season.

(a Starlog photo-guidebook, 1978) p65
In spite of the continuing controversy that surrounded Space: 1999 throughout its two seasons on TV, the show remained the most visually spectacular series ever aired on a weekly basis. Content-wise, the people in charge never quite decided whether to push for hardcore science-fiction, fantasy or metaphysics. While any astronomer would wince, the depiction of all the various planetary landscapes was usually well done.

1975: SPACE: 1999
(UK)ITC. Gerry and Sylvia Anderson unleashed this absurd 'sf' series on American and British audiences in 1975. An explosion of radioactive waste sends the Moon hurtling into deep space, taking with it a large lunar base & its inhabitants. Before long they enter other solar systems (the moon appears to be travelling at the speed of light) and encounter alien worlds, just as the characters in Star Trek had done. The cast included Martin Landau, Barbara Bain, Barry Morse, Nick Tate and Catherine Schell. The first season was produced by Sylvia Anderson and the second by Fred Freiberger, who had previously produced The Wild,Wild West and the third and final season of Star Trek. The special effects by Brian Johnson were the most outstanding feature in a series which ended in 1976.

Chapter on "Screen Trips" by Alan Frank: p85
Not surprisingly, Star Trek spawned imitators, the most considerable of which has been Space: 1999, made in Britain but with American leads, Martin Landau and Barbara Bain, to give it appeal for the American networks. The series' premise was that Moonbase Alpha, under the command of Landau's Captain Koenig, is doomed to wander the universe after the Moon itself was torn out of Earth orbit because of a massive explosion of nuclear wastes dumped on the satellite. Once in space, however, the adventures of the 300 or so reluctant passengers of the wayward satellite soon turn out to be a poor imitation of the format of Star Trek. The series' failure was due to two main factors. The first was that the scripts themselves were banal and their science fiction content was soon subordinated to mediocre adventure themes. The second, and potentially more damaging factor was that the leading characters were dull and uninteresting, falling back on stock stereotypes and emotional cliches so that they never became alive in any sense or were able to transcend their material. Even the inclusion later in the series of a female alien, able to metamorphose into other life forms, never succeeded in being anything other than a not very good plot gimmick.

Alan Frank (Octopus 1978) (p16)
In Britain, an attempt was made' to create a series that would duplicate the runaway success of Star Trek. The result, Space 1999, which debuted in 1975, failed to repeat history. In America and Britain it was not networked in a regular slot, which spelled death to the series. In many ways the format was too close to that of Star Trek. Instead of a space vessel cruising the universe, Space 1999 featured a similarly hermetically enclosed community adrift in the cosmos, only this time living on a portion of the moon blasted from the surface of the satellite into independent orbit. None of the regular characters, unlike the quirky but credible crew of Star Trek's spaceship Enterprise, managed to be anything more than conventional ciphers, the plots were mostly uninteresting and unconvincing, and only the series' production design and its special effects, directed at Bray Studios by Brian Johnson, who had worked on 2001: A Space Odyssey, impressed, particularly the meticulous miniatures and lunar landscapes.

by Suares and Siegel (Reed Books, 1979) (Text by David Owen) p24:
The most technically accomplished of all sci-fi TV shows was the short-lived Space 1999, whose Moonbase Alpha set was a genuine achievement.

(Ed Peter Nicholls, Granada 1979) (p559)
SPACE 1999 (John Brosnan) This British made series, created by the Andersons, was obviously inspired in part by the success of Star Trek. Here, too, the format involves a group of people travelling through the galaxy, visiting different planets and encountering strange life forms. But where the Star Trek characters travelled on a spaceship, the Space 1999 characters do their interplanetary wandering on Earth's runaway moon - an unwieldy gimmick that must have caused many frustrations to the writers. Despite excellent special effects and imaginative sets the series as a whole was strangely lifeless and bland, a fault that seems to beset most Anderson productions. The characters were stereotyped and the scripts humourless. The other major flaw with the series was a disregard for basic science which many critics saw as scandalous: stars are confused with asteroids, the Moon's progress through space follows no physical laws and parsecs are assumed to be a unit of velocity.

Stars are not confused with asteroids. Possibly this is an inaccurate impression of the opening of the episode Black Sun, where an asteroid is torn apart, and then the Alphans discover the black sun (black hole). The asteroid was moved off course by the black hole, it did not turn into the black hole.
The Moon's progress through space follows standard Newtonian physics, but does not take into account the vastness of distances in space.
Parsecs are mentioned in two episodes, The Taybor and Space Warp, and in both are units of distance.

TELEVISION (John Brosnan; p577) In 1975 Gerry Anderson, after the failure of UFO, created a pale imitation of Star Trek with his series Space 1999. Surprisingly, it enjoyed some success in America, but only briefly, and it ended after two seasons. The series represents a nadir in the quality of scientific thought in televised sf.

Also mentioned in entries on 'Scientific Errors' (p532, Peter Nicholls & John Sladek) "Space 1999 was a particularly bad offender" and 'Parsec' (p451, by Peter Nicholls). "We're travelling at 17 parsecs?" the hero of the TV series Space 1999 might erroneously cry."

Chapter "Where science fiction gets it wrong" by David Langford. p197
Television still gives plenty of amusement to bad-science fans. In recent years the worst offender by far was the series Space 1999 (1975), in which parsecs are used as a unit of velocity instead of a unit of distance; stars are confused with asteroids, sound travels in vacuum; there is daylight between the stars; and an explosion sends our Moon (undamaged) careering through space at faster than the speed of light.

Viewing the alien environments of Fireball XL5, the origin of the sophisticated imagery of the live action Space: 1999 is quite apparent. Those lucky enough to have had further opportunities to see more episodes from the second series of Space: 1999 of late will have appreciated the similarities despite the differences brought about by over a decade of technological advances in special effects. Imaginative storytelling combined with visual excellence created in the first series of Space 1999 not only Anderson's crowning achievement but also what has turned out to be the apogee of science fiction on the small screen. Regrettably, although it became a cult series overseas, as far as the ITV companies were concerned it was a ratings flop, so when that second series came along it was an item principally for export. Eight years on, there are still some British viewers who have not had a chance to see all the second series episodes, whilst others have enjoyed two or three screenings of each story (some featuring guest performances by Pamela Stephenson, Sarah Douglas and Lynne Frederick early in their careers).

DESTINATION MOONBASE ALPHA (1975) C Dir:Gerry Anderson. With: Martin Landau, Barbara Bain, Catherine Schell. (2 stars on a scale of 1 to 4)
A feature version of the Australian- made teleseries Space: 1999 consisting of two edited episodes. Landau is the commander of a space station called to investigate a planet invading the Earth's solar system, but first he must contend with a mysterious illness which is killing off his crew. Landau and Bain (then husband and wife) have a compelling chemistry on screen, but the same cannot be said for the abrasive clashing of the disco music score and the sterile futuristic atmosphere."'

ALIEN ATTACK (1977). Feature-length adaptation of several episodes from the British TV series Space: 1999, wherein the build-up of 'magnetic radiation' in a Nuclear Waste dumping site on the moon results in an explosion which fires the moon (and Moon-Base Alpha with 300-plus staff) out from Earth's orbit, and off on a journey towards the distant stars. The first half of the film deals with this, the second with an encounter with a wandering planet, Meta, a veritable Utopia of perfect harmony. Man meets and is dismissed by superior beings as being "a contaminating organism", not yet fit for Utopia. The special effects are as good as anything Star Trek ever offered, though there's less glamour and more pseudo-science in this space-opera, set-unlike the series-in 2100.

The Andersons' second venture into live-action SF was visually splendid but flopped owing to mediocre acting and, most of all, rotten scripts. The Moon, including a manned base, is blasted out of Earth's orbit by a nuclear accident. Cruising through the galaxy, the colonists meet and kill implacably hostile aliens.

Anderson returned to telefantasy (and the Moon) with Space: 1999, which, due to Anderson's wish to sell the series to the American market, starred Martin Landau, Barbara Bain and Barry Morse and cost more than all his other series put together. The premise was excellent, the Moon being blown out of Earth's orbit by a nuclear explosion. Unfortunately, despite a promising beginning, a clutch of guest stars including Anthony Valentine, Brian Blessed, Joan Collins, Peter Cushing, Christopher Lee and Leo McKern, and several well-remembered episodes - such as the extremely weird 'Black Sun' and the horrific 'Dragon' Domain' - the series was vacuous, slow-moving hippie drivel. A second season, made in 1976, tried to be a more standard adventure, and, in doing so, found new ways to be awful.

General editor David Pringle (Colour Library Direct [Carlton Books], UK, 1997); p146
Using models rescued from the wreckage of the series UFO, Gerry and Sylvia Anderson attempted an imitation of Star Trek which succeeded in running for two seasons (48 episodes) despite labouring under the terrible handicap of using the moon (or at least a fragment thereof) as an improbably fast moving space vehicle. The scripts collaborated with this absurd device in setting new standards of scientific illiteracy, and the ultra cheap special effects led British fans to dub it 'Space Nineteen Pounds and Ninepence', but success in the US kept the show going.

[This is probably the only review to ever accuse the special effects of being cheap!]

Although Landau, Bain and Morse were all competent actors who had done good work on other shows, Space: 1999's scripts gave them no chance to conjure up credible performances and, at times, they seemed hilariously incompetent as they soldiered on bravely against the odds. The combination of atrocities was almost bad enough to qualify the show as a kitsch classic, but its real achievement was to make Star Trek seem sophisticated by comparison.

(The series profile was alongside a sidebar on "kitsch classics", which pronounced the show too bad to be kitsch. One photo - a Year 2 publicity shot of Maya in burning Eagle- was captioned: Aaargh! All writers of TV SF need to master this useful item of dialogue; more as can be [sic] added if necessary.)

by Daniel O'Brien (Reynolds and Hearn, UK, 2000); p104-107
The potential is there, yet neither executive producer Anderson nor his creative team ever gave the material a real sense of style or purpose, perhaps a reflection of the show's hasty, stop-gap conception. ...The ersatz Kubrick approach just doesn't work, no matter how much the directors cut to lingering soft focus close-ups of Barbara Bain. The crew of Moonbase Alpha is made up of bland, ill defined characters whose blank faced interaction creates little sense of warmth or even professional camaraderie. ...The scripts tend to offer a promising initial situation, sometimes quite intriguing, but rarely develop ideas into strong storylines. Occasionally, by some mysterious cosmic alchemy, the show got something right, notably with the episode Dragon's Lair. ...This is efficient, effective horror.

ILM's artists were proud of their spaceship models, but there was already a major problem with one of them. Local stations across the United States had started screening Space: 1999, a science fiction TV show imported from the UK, in late 1975. It was set on the moon, which is knocked out of orbit and into interstellar space by a nuclear explosion. Space: 1999 had been aimed at the US market, with American actors and a hefty $3 million special effects budget for the first season. It was bad enough that the characters mentioned a "mysterious force" that was supposedly guiding the moon's journey or talked about the problems of "going to the dark side" (of the moon). Worse that the moonbase's major ship, the Eagle, looked a lot like Han Solo's long, sleek pirate vessel, which ILM model makers had just completed, and which Lucas had just named in the fourth draft: the Millennium Falcon. Eagle, Falcon: Lucas was going to look like a plagiarist.
So ILM had to come up with a bold and costly new design. The original Falcon had cost $25,000 - a third of the whole model budget. It was reused as the rebel ship at the beginning of the movie, the Tantive IV.

The Space: 1999 SFX was a lot less than $3 million, which was half the total budget of the show. There are various mysterious forces in different episodes, not necessarily benevolent. No-one talks about "going to the dark side". The book does not mention that George Lucas visited Brian Johnson at the Space 1999 SFX stages and asked him to work on Star Wars (he couldn't for he first film, but he worked on the sequel, The Empire Strikes Back).
